Configure the Log Directory for Multiple Nodes

Configure the Log Directory for Multiple Nodes

When the Data Integration Service runs on primary and back-up nodes or on a grid, a Data Integration Service process can run on each node with the service role. Configure each service process to use the same shared directory for log files.
When you configure a shared log directory, you ensure that if the master service process fails over to another node, the new master service process can access previous log files.
Configure each service process with identical absolute paths to the shared directories. If you use a mapped or mounted drive, the absolute path to the shared location must also be identical.
For example, a newly elected master service process cannot access previous log files when nodes use the following drives for the log directory:
  • Mapped drive on node1:
    F:\shared\<Informatica installation directory>\logs\<node_name>\services\DataIntegrationService\disLogs
  • Mapped drive on node2:
    G:\shared\<Informatica installation directory>\logs\<node_name>\services\DataIntegrationService\disLogs
A newly elected master service process also cannot access previous log files when nodes use the following drives for the log directory:
  • Mounted drive on node1:
    /mnt/shared/<Informatica installation directory>/logs/<node_name>/services/DataIntegrationService/disLogs
  • Mounted drive on node2:
    /mnt/shared_filesystem/<Informatica installation directory>/logs/<node_name>/services/DataIntegrationService/disLogs
